John developed hearing problems after the second cisplatin dose and they continued for the rest of the treatment. Some tinnitus - his his case a combo of buzzing and ringing- as well as general distortion. Not only did he say 'pardon?' a lot any abrupt loudish noise would make him jump a mile.
We were told that the cisplatin and the radiation might negatively affect his hearing but, for the most part ( 6 months post-treatment), his hearing has returned to close to normal although he still has some ringing from time to time.
